AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
330 AM CST TUE DEC 30 2008

.SYNOPSIS...
S/W OVER THE PACIFIC NW AT 00Z TUESDAY WILL MOVE RAPIDLY EAST
SOUTHEAST REACHING WI BY 00Z WEDNESDAY.  ASSOCIATED SURFACE LOW
CURRENTLY OVER THE WESTERN SD WILL MOVE INTO NORTHERN IN BY THIS
EVENING.

&&

.SHORT TERM...TODAY AND TONIGHT...
FOLLOWED THE GFS SOLUTION FOR TODAY AND TONIGHT BASED ON ITS BETTER
INITIALIZATION OF THE LOW DEVELOPING OVER THE NORTHERN PLAINS AND
ITS MORE NORTHERN FORECAST TRACK WHICH IS SUPPORTED BY DEVELOPING
BAROCLINICITY ACROSS NORTHERN IOWA AND BEST PRESSURE FALLS CENTERED
NEAR KFSD AT 08Z. THE GFS HAS THE SURFACE LOW OVER EAST CENTRAL IA
BY 18Z.  EXPECT A GOOD REBOUND IN TEMPERATURES TODAY ESPECIALLY IN
THE SOUTH WHICH WILL BE IN THE WARM SECTOR ALL MORNING. COLDER AIR
WILL ALSO BE LAGGING THE PASSAGE OF THE SURFACE LOW BY A COUPLE OF
HOURS ALLOWING ADDITIONAL WARMING DUE TO DEEP MIXING IN INCREASING
W-NW FLOW DURING THE EARLY AFTERNOON.  HAVE UPPED TEMPS A COUPLE OF
DEGREES IN THE SOUTH HALF.  NRN HALF OF THE CWFA WILL NOT SEE QUITE
AS BIG OF A RECOVERY TODAY DUE TO MORE CLOUDS AND SE SURFACE WINDS
THIS MORNING.  KEPT TEMPS HERE IN THE MID 30 AND BUMPED TEMPS IN THE
SOUTH TO AROUND 50.  BASED ON THE TRACK AND TIMING OF THE H8 LOW
CWFA SHOULD REMAIN DRY THROUGH 18Z WITH SNOW STAYING ACROSS SOUTHERN
IN CENTRAL WI.  MAINTAINED LOW CHANCE POPS IN THE FAR NORTH THIS
AFTERNOON AND IN THE NORTHEAST THIS EVENING WITH POSSIBILITY OF -SN
OR FLURRIES IN THE STRONGER CAA AND WRAP AROUND MOISTURE BEHIND THE
SURFACE LOW. STRONG NW WINDS WILL ALSO BE A FACTOR LATE THIS
AFTERNOON AND THIS EVENING WITH 40 TO 45KTS AT H925 AND 40KTS TO
50KTS AT H850 SPREADING OVER THE AREA LATE THIS AFTERNOON.  FORECAST
SOUNDINGS SUPPORT MIXING THROUGH 900MB SUGGESTING MAX WIND GUSTS
APPROACHING 40 KTS. THESE WINDS WILL BE CLOSE TO ADVISORY
CRITERIA...ESPECIALLY WEST OF THE MS RIVER.  SINCE THE STRONGER
WINDS WILL BE MOVING IN AFTER DARK WHICH DOES NOT FAVOR MAX GUST
POTENTIAL...WILL NOT ISSUE A WIND ADVISORY YET.  THE DAY SHIFT WILL
BE ABLE TO MONITOR WINDS TO OUR WEST AND ISSUE AN ADVISORY IF NEEDED
WELL IN ADVANCE OF THE STRONG WINDS MOVING IN.  WINDS SHOULD DIE
DOWN TONIGHT AS HIGH PRESSURE MOVES INTO WESTERN IOWA.  WE SHOULD
SEE SOME CLOUDS...ESPECIALLY IN THE NORTH THIS EVENING WITH
CAA...WITH CLEARING EXPECTED OVERNIGHT.  LOWS TONIGHT TO BOTTOM OUT
IN THE SINGLE DIGITS NORTH AND THE MID TEENS SOUTH.     ..DLF..

.LONG TERM...WEDNESDAY THROUGH NEXT MONDAY...
ON WED...MAINLY A CHANNELED VORT COMPLEX WILL MIGRATE TO THE EAST OF
THE CWA AS A BOUT OF UPPER RIDGING SWEEPS ACRS THE UPPER MS RVR
VALLEY AND WESTERN GRT LKS THROUGH THU MORNING. LATEST RUN 00Z
SHORT RANGE MODELS...AS WELL AS THE EUROPEAN MODELS ARE IN GOOD
AGREEMENT WITH A STRONG LLVL HIGH OF POSSIBLY 1035 MB STRENGTH
ENGULFING THE REGION IN THE WAKE OF THE TUE NIGHT SYSTEM. FRESHLY
ARRIVED H85 MB COLD POOL OF -10 C TO -13 C EXTENT WILL MODIFY ONLY
SLIGHT AS WED PROGRESSES...SUPPORTING HIGHS ONLY IN THE UPPER TEENS
IN THE NORTH...TO THE UPPER 20S TO AROUND 30 IN THE SOUTH. FOR NEW
YEARS EVE...EXPECT A QUICK DROP-OFF WITH MID EVENING LOW TEMPS
BEFORE THE NEXT APPROACHING SYSTEM IN PROGRESSIVE WEST-
NORTHWESTERLIES AND EXITING LLVL HIGH PRESSURE COMBINE TO INDUCE LLVL
RETURN FLOW AND STEADY TO SLOWLY RISING TEMPS LATER WED NIGHT INTO
THU MORNING. EXTENT OF CURRENTLY PROGGED WAVE ENERGY AND PHASING
SUPPORT A RATHER VIGOROUS LLVL CYCLOGENESIS PROCESS WHICH RESULTS
IN A SUB 1000 MB SFC LOW OVER LK SUPERIOR BY FRI MORNING. WILL
TREND HIGH TEMPS UP ON THU IN WAA REGIME SOUTH OF THIS PROCESS...AND
THE UPCOMING DAY SHIFT MAY HAVE TO BUMP UP THESE VALUES EVEN FURTHER.
FORCING OFF THIS WAVE AND WAA WING TYPE PROCESSES SHOULD INDUCE LIGHT
SNOWS INTO THE NORTHWEST THIRD OF THE DVN CWA BY THU AFTERNOON...WITH
LIGHT SNOW OR FLURRIES AFFECTING ALMOST THE ENTIRE CWA INTO THU
NIGHT. ACCUMULATIONS STILL LOOK TO BE AN INCH OR MAINLY LESS CWA-WIDE
BY FRI MORNING. THE MODELS THEN VARY ON EXTENT OF FOLLOWING COLD DUMP
LATE THU NIGHT INTO FRI WITH THE NEW 00Z GFS THE COLDEST AND
ADVERTISING H85 TEMPS FROM -15 TO -20 C IN THE NORTH HALF AND HIGH
TEMPS IN THE TEENS. THE ECMWF SHUTTLES BRUNT OF THE LLVL COLD POOL TO
THE NORTHEAST...BUT STILL HAS COOL THERMAL PROFILES THIS FAR SOUTH
FOR HIGHS IN THE LOW TO MID 20S AND THAT IS WHAT WILL BE ADVERTISED
IN THE GRIDS. VORTS SPOKES EMBEDDED IN A STEEPENING CYCLONIC FLOW AND
THE INCOMING CAA REGIME SHOULD MILK OUT FLURRIES OR LIGHT SNOW
SHOWERS ON FRI.

DEPENDING ON NORTHERN-SOUTHERN STREAM PHASING WITH THE NEXT SLUG OF
WAVE ENERGY...A SNOW CHANCE LOOKS ON TAP FOR LATE SAT AND SAT NIGHT
POSSIBLY TO ADVISORY CRITERIA IN PORTIONS OF THE LOCAL AREA. AND
LOOKING AT DAY 7 TO 8...THE MEDIUM RANGE SOLUTIONS STILL ADVERTISING
AN OMINOUS LOOKING SOUTHERN PLAINS LOW PULLING OUT-EJECTING
NORTHEASTWARD ALONG THE GOLDEN PATH FOR A SIGNIFICANT SNOW STORM IN
OR NEAR THE DVN CWA NEXT TUE INTO TUE NIGHT.      ..12..

&&

.AVIATION...
S TO SE SFC WINDS AND VFR CONDITIONS WILL BE OVER ALL TAF SITES THIS
MORNING AHEAD OF SURFACE LOW MOVING ACROSS WRN IA.  LOW TO PASS EAST
OF ALL TAF SITES BY 21Z WITH INCREASING W TO NW WINDS IN THE WAKE OF
THE LOW.  EXPECT W-NW WNDS GUSTING AROUND 35KTS AT MOST SITES FROM
21Z TO 03Z WITH WINDS DIMINISHING TO 10 TO 15 MPH AFTER 06Z.  SC
MOVING SOUTH BEHIND LOW MAY BRING SOME MVFR CIGS THIS EVENING TO KDBQ
AND KCID. THESE SITES MAY ALSO SEE SOME -SN THIS EVENING...HOWEVER
NO VSBY RESTRICTIONS ARE EXPECTED. CIGS TO DISSIPATE AFTER 06Z.
